A Chesapeake portrait, painted by almost a thousand words

Combing the beach, I stoop to pick up an essay for my upcoming college nature writing class. It’s a reddish, roundish pebble, tumbling in the clear lapping waves during a campout to the vanished community of Holland Island.

For a couple of centuries, before erosion forced Holland’s people to the mainland, my pebble was a brick, proud and sturdy and eminently useful in its uniform rectangularity for stacking when constructing a home’s foundation with precise edges and level tops.

Made by humans, who have the corner on corners as no other species, the brick has been reshaped by nature, which embraces the rounded, the curved and the meandering, from spiral galaxies and loopy marsh creeks to the shells of whelks.

The brick/pebble thus becomes distilled and refined to a rich essential — to an image — the straight versus the curved, the human versus the natural.

This gives my fledgling essayists a useful lens. Later in the semester we’ll look at farm drainage ditches versus swamps, the former doing one thing very well — whisking rainwater from cropland; the latter doing no one thing spectacularly — just nurturing life in diversity unknown to the ditch and the cornrow.

They may expand their view further, to the pavement and the curb, the gutter and the storm drain, versus the woody debris and leaf duff of the forest floor; they may ponder which of those landscapes, during a downpour, a trout in a stream would most like living next to.

A photograph may be worth a thousand words, but a good word image is worth a hard drive’s worth of photos. Word imagery is especially important when you are writing to explain a six-state, 64,000-square-mile, Atlantic-to-Susquehanna ecosystem like the Chesapeake Bay. Here are a few of the images I’ve found useful over the decades:

The Skinny Bay

From Havre de Grace, MD, to Virginia Beach, the Bay’s about a million feet long — and up to 100,000 feet wide. Yet the average depth is around 21 feet. So many implications flow from that.

Large as it looks, the estuary has scant water to dilute runoff from Cooperstown, NY, to Altoona, PA, to Lynchburg, VA, so how we use the land matters big time for water quality.

This essential shallowness also means light penetrates to the bottom copiously, growing lush habitats of seagrasses, which support waterfowl and waterfowl hunting cultures and soft-crabbing.

It also means that the winds push water around so easily they are often more important, ecologically, than the tides. it also dictates the classic “deadrise” designs of skipjacks and other watermen’s crafts evolved to make their living in skinny water.

Wet

The Chesapeake ecosystem for most of time is widely understood to have been green, with forests covering most of its watershed. But thanks to the scientific detective work of people like Grace Brush of Johns Hopkins University, we now comprehend how much of the landscape was also wet, dammed and ponded by millions of beavers.

Brush’s work, now in book form — Decoding the Deep Sediments, available from Maryland Sea Grant — shows how prevalent the pollens of aquatic plants are in sediment cores that allow us to look back through what was washing into the Bay in centuries past.

Green and wet: Why does it matter so much? Because that landscape fostered the healthiest Chesapeake, the landscapes we should most try to emulate and restore.

Ask yourself, WWBD — what would beavers do?

Edges

Edges are inherently interesting: the gradations of color and texture that artists employ to draw the eye to the glorious intersections of the seasons, adorned by the great migrations of fish and fowl they trigger.

Life loves an edge. Hunters who prowl the seams where forest meets field know this, as do fishermen who troll the dropoffs from shallows to channels, as do blue herons and egrets, nesting eagles and beachcombers (I prefer the waterman’s term for them: proggers.)

The Bay, with around 11,000 miles of tidal edges, is at the heart of the heart of this phenomenon. That includes the overwhelming preference of humans to also locate along the edge, drawn by everything from places to discharge waste, cool their power plants and hoist drinks to the sunset.

The search for peaceful co-existence between humans and the rest of edge-loving nature is a fundamental tension that runs through much of my writing.

Ecosystem Services

If you would be popularly read, avoid such terms, but not what they include. Consider the oyster. The revelation in recent decades of their immense values in filtering and cleansing Bay waters has fundamentally changed the way we regard them — not only as a tasty food and commerce by the bushel, but also as sanctuaries for the health of the Bay.

Some scientists say it’s likely that the reefs, built by oysters spared from harvest to form undisturbed, undredged, untonged communities, are at least as valuable for habitat as for their filtration.

And One Last Favorite…

Horseshoe crabs are living fossils for whom the rise and fall of dinosaurs was just a short span in the species’ history. When they scrabble onto remote beaches in May and June, with nothing else in the scene but the full moon gleaming on their bronze-colored shells from above, sand and the lapping of saltwater below — that’s as close as you will ever get to traveling back in time half a billion years.

Great read and a wonderful photo. Steve in Colorado

What a great reminder from Tom Horton about the power of language, especially figurative language. As far back as Moses Maimonides thinkers have understood that metaphoric language enables the human mind to grasp ideas in ways that surpass conventional logical thinking. That's one reason creative nonfiction can be a powerful tool, especially when Tom Horton is wielding the pen.

My education after Forestry School continued in 1972 when I began working at the Smithsonian Institution's Environmental Research Center near Annapolis in many ways because of the work and knowledge of a school-friend, Jake Page, the now-late Editor of Smithsonian Magazine, plus reading and hear Tom Horton for so many years. The Bay Journal continues my education in retirement and enjoyment here in Baltimore.

"Made by humans, who have the corner on corners as no other species, the brick has been reshaped by nature, which embraces the rounded, the curved and the meandering, from spiral galaxies and loopy marsh creeks to the shells of whelks." -- this is deep, philosophical. Summarizes all what we are doing wrong and how to make them right! Beautiful, beautiful piece. Kudos to the writer!
